Xofluza (baloxavir marboxil) is an antiviral medication approved by the U.S. Food and Drug Administration (FDA) for the treatment of influenza (flu) in people aged 12 years and older. It is designed to alleviate symptoms by attacking the flu virus and stopping its replication. This medication is particularly noted for its effectiveness in treating symptoms when administered within the first 48 hours after they begin.
Xofluza operates by inhibiting a specific enzyme called endonuclease, which the flu virus requires to replicate within the human body. By blocking this enzyme, Xofluza disrupts the viral replication process, thereby limiting the spread of the virus and reducing the overall severity and duration of the illness. This mechanism of action distinguishes Xofluza from other antiviral medications, which may target different stages of the viral life cycle.
Xofluza Boxed Warning
Patients treated with Xofluza, especially those with underlying health conditions, are at an increased risk of developing bacterial infections. Use of Xofluza can potentially lead to the suppression of immune system responses that are crucial in fighting bacterial pathogens. It is critical for patients and healthcare providers to monitor for signs of secondary bacterial infections during and after treatment with Xofluza.
Xofluza Precautions

- Vaccine Interference: Xofluza may interfere with the effectiveness of live influenza vaccines. It is advisable to wait for at least 48 hours after taking Xofluza before receiving a live flu vaccine.
- Renal and Hepatic Impairment: Patients with renal or hepatic impairment should use Xofluza with caution. Reduced doses may be necessary to avoid increased exposure and potential toxicity.
